Document Type and Number:
WIPO Patent Application WO/2023/176855
Kind Code:
A1
Abstract:
According to the present invention, it is possible to obtain a grain-oriented electromagnetic steel sheet containing a predetermined composition and comprising a forsterite coating film having high peel resistance for processing with a smaller bending radius, even in an inhibitor-less component system, by positioning one or both of the peak intensities of Ti and Nb obtained through GDS analysis on the iron side at a thickness greater than 1/2 of the thickness of the forsterite coating film.
